This changelog line is missing: * Fallback to factory default HD firmware alias, not to <unknown device> And what that does? At the end of nobootloader installation, d-i prints out a line the user installing the system is supposed to type into firmware prompt to make it find kernel on machine boots/reboots. The 'path' variable in question is the firmware device path used in the printed line on Pegasos machines. I've replaced the technically invalid firmware path '<unknown path>' with the device alias 'hd' which works out fine when the machine has only one HD, or if the user installs the system on the first HD when the machine has more than one drive. In my wheezy installer tests it always falls back to <unknown path>. This happens because the kernel internals changed since the original Pegasos code in nobootloader was written. To fix it properly, it requires significant rewrite. Which is not worth. I would rather spend more time into making Grub2 installer working on Pegasos and other PowerPC machines. But this change is too late for Wheezy. It has to wait for Jessie. In the meantime, the changes made in nobootloader version 1.35 are enough to make it work for wheezy. Milan
